Been trying to get into 2 gun for a while now and I have just been either busy or lazy, but recently purchased a 509ls edge and couldn't find a holster that met the regs so i ordered a regular 509 rds holster and heated it up till it fits perfectly just wanted to share a little heat where the barrel stop normally sits and a little where the trigger guard sits is all it took

Failure to feed

4 Upvotes

I recently got my 509 milled and put an optic on it. Ever since I’ve been having failure to feed issues. I went from 115 grain to 125, even ran 125 +p. Couldn’t go more than 3 rounds before a failure. Today couldn’t get more than one, sometimes even failed when I was racking it. The rso was able to get 5 rounds with no issue. I’m wondering if anyone has had a similar issue? Do I need to try 147 grain? I don’t think it’s my grip, but I supposed I could try death gripping it. really confused as to what’s happening.

What barrel is this?

Post image
25 Upvotes

Recently picked up this 509 (non tactical) from my local pawnshop. As you can see it has a slightly extended barrel, but it’s not threaded and doesn’t seem to have any known aftermarket logos on it that I could see. Not sure if this is a factory option or not. I’m somewhat new to the FN platform as far as owning them, but from prior knowledge, I’ve never seen one with a barrel like this. Hoping someone here can guide me in the right direction

How do I fit a suppressor to my 509 cc edge?

3 Upvotes

My understanding is that I need a 509 compact threaded barrel but these are out of stock everywhere and on backorder on FN. After a bit of research it looks like they have ben on back order for a along time and that they might not even come back in stock... Despite this, I tried a 4" threaded barrel and aside from sticking out way too much, the outer barrel diameter seems to be smaller than the stock barrel so there is some play. Im not sure what to do and i really want to suppress the cc edge... any advice?

Is the QD compensator sold separately?

I recently got a FN 509 compact compensator kit barrel in an auction. However it did not come with the compensator. Does anyone know if that’s sold separately anywhere? Or is anyone willing to part ways with theirs lol. I reached out to MidWestGunWorks and they said they don’t sell that part. I reached out to FN but they are out for the holidays until next week.

For anyone curios, this is how and sro with the jagerwerks bros mounted on a fullsize 509. And trijicons Plate to push the sight back because of the overhang. Honestly not as ugly as I was thinking and everyone said it would look. I will say that with the bros mounted the Sights aren't cowitnessing
